柔性导电薄木的微观结构与导电性能研究

Microstructure and Conductivity Properties of Flexible Conductive Wood Slices

为开发木基柔性导电材料,采用导电高分子对柔性薄木切片进行原位聚合,制备薄木-聚吡咯(PPy)和薄木-聚苯胺(PANi)两种导电材料,并对其微观形态、结构与导电性能进行研究。结果表明:通过聚合,薄木切片表面成功地附着了一层PPy纳米颗粒或PANi纳米棒,附着量和薄木的导电率均随聚合时间的延长而增加;弯曲角度对导电薄木的导电性能影响很小,电导稳定性优良,作为柔性电极材料,具有潜在的应用价值。

Flexible wood slices were treated by in-situ polymerization of conducting polymers for developing conductive materials. Two kinds of conductive materials, such as wood slice/PPy and wood slice/PANi, were prepared and their microstructure and electrical properties were evaluated. The results showed that the PPy nanoparticles or PANi nano-rods were attached to the surface of the wood slices. With extending the polymerization time, the mass loading of the conducting polymer and conductivity of the slices increased. Bending angles had little effect on the conductivity of the slices. As a flexible electrode material, it showed stable conductivity with application potentials.
